A central heating power flush is a great way to clean out your system and make sure it is working at its best.

What is a power flush?

A power flush is a chemical solution that cleanses your central heating system and removes any elements inside of pipes, such as rust or debris that may be causing it not to work as well. If left inside of your system, it can cause you serious problems to your home heating. Over time the water in your pipes, boiler and radiators produces unwanted dirt and can cause your radiators to not give out as much heat or cause your boiler to break down completely.

A power flush removes the sludge in your system, preventing blockages and central heating inefficiency. This means that your radiators and your boiler can work more efficiently when heating your home, prolonging the life of your heating system.

Signs that you need a power flush

Below are some of the most common signs that your central heating system may need a power flush. It is best to get the advice of a gas safe registered engineer who can advise you on whether you need a central heating power flush.

Your radiators and boiler are noisy

Leaks coming from your radiators

Your radiators have cold patches, particularly at the bottom

Your boiler keeps breaking down and needs to be restarted

Excessive noise from the boiler or the heating system pump

Your central heating takes longer than expected to warm up

Cloudy tap water

Some radiators struggle to heat up as well as others

Your radiators are not getting warm, even when the boiler is turned on

No water escapes when you bleed a radiator

If when you bleed a radiator, the water is discoloured.

It is a good idea to think about having a power flush on your whole central heating system when you have a new boiler installed. A power flush to your central heating system is recommended every 5-6 years to keep your boiler in tip top condition and working as you’d expect.

How long does a power flush take?

It varies depending on your house size and heating system as to how long a power flush will take to perform. A power flush will take less time to perform if you have a combination boiler or sealed system because there isn’t a need to cap off the cold feed and expansion piping.

It usually takes around half a day to power flush a system thoroughly. You can typically expect a power flush in a three bedroom house with a vented system to take around 5 hours to perform.

Who should perform a power flush?

We work with Fernox, the global market leader of water treatment chemical products, so you can be rest assured in the standard of quality and expertise. It is always advised to have a power flush performed by a qualified professional. Our reputable engineers are trained to handle the specialist chemicals and equipment that a power flush requires.
